Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2012-0987; Directorate Identifier 2012-NM-130-AD; 
Amendment 39-17317; AD 2013-01-03]
RIN 2120-AA64

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
The Boeing Company Model 737-300, 737-400, 737-500, and 757-200 series 
airplanes. This AD was prompted by a report of damage caused by 
electrical arcing to the wires that connect seat electronics boxes 
(SEBs). This AD requires installing a new relay and doing certain 
wiring changes of the entertainment control switch. We are issuing this 
AD to prevent power from being supplied to passenger seats when the 
entertainment control switch is in the OFF position, which could cause 
an electrical shock hazard resulting in serious or fatal injury to 
maintenance personnel.

DATES: This AD is effective February 22, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of February 22, 
2013.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM published in the Federal Register on September 20, 2012 (77 
FR 58325). That NPRM proposed to require installing a new relay and 
doing certain wiring changes of the entertainment control switch if 
necessary.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the proposal 
(77 FR 58325, September 20, 2012) and the FAA's response to each 
comment. Boeing concurred with the contents of the NPRM. American 
Airlines stated that it understands the basis for the proposed AD and 
that it does not operate any of the airplanes having serial numbers 
identified in the NPRM.

Supplemental Type Certificate (STC) Winglet Comment

    Aviation Partners Boeing stated that the installation of winglets 
per STC ST01518SE (http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgSTC.nsf/Frameset?OpenPage) does not affect accomplishment of 
the proposed requirements.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
the AD as proposed--except for minor editorial changes. We have 
determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (77 FR 58325, September 20, 2012) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (77 FR 58325, September 20, 2012).

Costs of Compliance

    We estimate that this AD affects 28 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. Subtitle VII: Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701: ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    This AD will not have federalism implications under Executive Order 
13132. This AD will not have a substantial direct effect on the States, 
on the relationship between the national government and the States, or 
on the distribution of power and responsibilities among the various 
levels of government.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
